SHINGLE.

v Application filed November 11, 1925. Serial No. 68,363.

This invention relates to shingles and has for its object the provisionof a device for locking the edges of a shingle in position to preventthe shingles from curling or being bent outwardly-fronttheir normalrelation with each other. .1

A further object of the invention is the provision of a shingle havinginterlock ng means with adjacent shingles for securing the ends of theshingles together in such manner that eachrow of shingles will be heldtogether and thus distortion or curling of the shingles will beprevented.

This invention will be best understood from a consideration of thefollowing detailed description, in View of the accompanying drawingsforming a part of the specification; nevertheless it is to be understoodthat the invention is not confinedto the disclosure, being susceptibleof such changes and modifications which shall define no materialdeparture from the salient features of the invention, as expressed inthe appended claims.

In the drawings:

Figure 1 is a view in perspective showlng a roll of roofing material cutto provide the shingles constructed in accordance with the principles ofmy invention.

Figure 2 is a view in perspective of a section of a roof on which havebeen applied the shingles constructed in accordance with the principlesof my invention.

Figure 3 is a detailed perspective view showing the locking means forthe ends of the shingles,

Figure 4 is a plan view of the section of a roof showing the applicationof the shingle at the starting corner of the roof.

Figure 5 shows the shingle in Figure 1 along the edge of the roof whenthe shingles are initially applied. The free edge 12 of the section 11is cut with V-shaped slits 13 which form interlocks with other slits onthe shingles 14 which are afterwardsand successively cut from the roll10.

The shingles 14 .when placed in a horizontal osition are provided withdepending V-s iaped portions 15 along the lower edge and notchedportions 16 along their upper edge with the apex 17 of the notchedportions being in vertical alinement with the apex 18 of the V-shapeddepending portions. Each of the depending portions 16 are provided withslits 19 parallel to one side edge and at right angles to the other sideedge to form an interlocking lip 20 along one edge and where one sideedge of an end depending portion 15 terminates along the side edge isprovided a V-shaped slit 21 which is similar to the slit 13 in section11.

It will be noted that the V=shaped notches 21 are extended across theshingle and are located adjacent the apex of the V-shaped notches 22formed between a pair of the V-shaped depending portions 15.

One method of applying the shin le is shown in Figure 2 in which theshing cs 14 are disposed transversely of the roof so that the unexpose-dportions of the shingles will appear as diamonds with the section 11located along the lower starting edge of the roof 23. i

When the shingles are applied as shown in Figure 2 the lips 20 areinterlocked with the lips 24 formed by the V-shaped slits 21 so thatthelip 20 will be always placed below the lip 24Lv By such aconstruction,

"however, the free end of the lips which are liable to curl during warmweather when the shingles have been applied or adapted to be raised bywind storms, will thus be locked and form substantially one solid sheetacross the roof and thereby prevent lifting of any portion of theshingle at any time.

It will be noted that a portion 25 of the shingle overlaps the upperportion of each shingle and which forms a shed to prevent seepage ofrain between the shingles. As shown at 17 in Figure 4 the portions 26which extendbeyond the edge 27 of thereofare sheared ofi'. The sectionswhich are cut 0E at the end of the roll are applied as shown at-11 inFigure 4 so that a double layer of I roofing is applied at this point.

Referring more particularly to Figure 5 a different application of theshingles is shown and in which the shingles are disposed diagonallyinstead of transversely and instead of the shingles appearing as diamondshaped as in Figures 2 and 4 they appear as squares extending verticallyand horizontally in op- E.
